Hi:

I don't see a 68SSR.

The 3 BIOS updates are for the 68SRR BIOS.

If you made a typo and your notebook has a 68SRR BIOS, then you can use any of them.

You would probably want to use the latest one (F.65).

One important note:  If your notebook is running fine and you update the BIOS and things don't work right afterward, you can only go back to version F.63, so think about it before taking the risk.

Read all of the release notes for the various BIOS updates to help you decide what you want to do.

If you look at the revision history on the link I posted, it shows the BIOS you have installed at the very bottom (F.0A).
